“入体原则”在冲模工作零件设计中的应用

The Application of "Principles into the Body" in the Design of Working Parts of Die

冲模工作零件工作部分尺寸的计算是模具设计的关键环节。因为工作部分尺寸精度关系到制件的精度、表面质量和模具的使用寿命。但在计算公式中的制件公差、模具的制造公差及磨损量必须转化为合适的标注形式才能保证工作尺寸的计算精度和模具的使用寿命。只要紧抓"入体原则"这把钥匙,就能开启设计计算过程中的种种疑问从而保证计算结果的准确性和合理性。

Calculation of working parts of die because the working part dimensional accuracy size of working part is the key of die design, is related to the product precision, surface quality and die life. But the product tolerance, the manufacturing tolerance of die and the wear in the formula must be converted into the appropriate annotation form to ensure the accuracy and the service life of the die size. As long as the grip ＂principles into the body＂ the key, all sorts of questions in the design calculation process can be opened to ensure the accuracy of the calculation results and rationality.
